CROSs border Swiss TIMES Electricity Model (CROSSTEM)

The Cross border Swiss TIMES Electricity Model (CROSSTEM) is a multiregional electricity model
of five countries, viz. Austria, Switzerland, Germany, France and Italy.

CROSSTEM regions

The model optimises electricity supply for an exogenously given electricity demand over a long time horizon
(to account for long term policy goals and investment decisions) while simultaneously representing
sufficient intra-annual detail (i.e., seasonal, weekly and hourly) to account for variations in electricity
supply and demand. The model encompasses the future electricity demand, a wide range of electricity
generation technologies and related electricity and environmental policies of all the five countries.

Intra-annual details in CROSSTEM

The analytical framework used to develop the CROSSTEM model is the Integrated MARKAL/EFOM
System framework (TIMES). TIMES is a perfect foresight, technology rich, cost optimization modelling
framework, which identifies the "least-cost" combination of technologies based on their operation
characteristics to satisfy given demands under given technical and policy constraints
(Loulou, Remne, Kanudia, Lehtila and Goldstein, 2005). The CROSSTEM model is an extension to
the Swiss TIMES Electricity Model (Kannan and Turton, 2011).
